Module Properties dialog box - Limits page parameters (5094-OF4IHS, 5094-OF4IHSXT)

Description

Indicates the maximum value that the output can take within the process with a range from -1.0E11 through 1.0E11. The default value is 100. The value must be greater than the Low Clamp value. If an output above the high limit is requested, the HLimit alarm is set and the output signal remains at the configured high limit. Output clamping does not apply in Program mode and Fault mode.

Indicates the minimum value that the output can take within the process with a range from -1.0E11 through 1.0E11. The default value is 0. The value must be less than the High Clamp value. If an output below the low limit is requested, the LLimit alarm is set and the output signal remains at the configured low limit. Output clamping does not apply in Program mode and Fault mode.

Disables all alarms.

Allows the latch clamp alarm to remain latched. This can be useful if alarm conditions need to be acknowledged by an operator.

Enables output ramping during Run mode. Output changes are limited to the maximum ramp rate during Run mode.

Tip:

Ramp in Run Mode

must be selected when Enable HART is selected.

The value for the ramp rate, which defines the maximum rate at which the output is allowed to transition in Engineering Units/Sec.

Allows the latch rate alarm to remain latched. This can be useful if alarm conditions need to be acknowledged by an operator.

Enables the detection of whether a load was disconnected.
